WD140-N 140-160 MHz Base Station Dipole Antenna DESCRIPTION
WD140-N
140-160 MHz Base Station Dipole Antenna
DESCRIPTION
Base station antenna conceived by using an innovative feed system
studied and applied to have highly symmetrical radiation pattern in
both planes (E and H). It’s completely computer designed to get high
performances of gain and front-to-back in the working band. All
aluminium parts are protected by anodized treatment, hardware are
of Stainless steel or zinc plated steel, mounting bracket is of extruded
aluminium for the best strength and the connector is placed in rear
position for an easily access. To increase the antenna gain please install
it in vertical stacked array. Patent pending applied.
